The L-Acoustics KUDO is a versatile, large-format bi-amp 3-way line array enclosure known for its unique “K-LOUVER” technology, which allows for mechanical adjustment of horizontal directivity. This flexibility enables the system to function as either a variable-curvature vertical line source or a constant-curvature horizontal line source, effectively performing as eight different loudspeakers in one.

Audio Performance & Transducers

The KUDO utilizes a coplanar symmetric arrangement to achieve consistent horizontal coverage across its frequency range.

• Low Frequency (LF): Two 12-inch weather-resistant bass-reflex drivers, each with a 4-inch voice coil.
• Mid Frequency (MF): Four 5-inch high-efficiency transducers mounted in a V-shaped configuration.
• High Frequency (HF): Two 1.75-inch diaphragm compression drivers coupled to individual DOSC waveguides.
• Crossover Points: Managed at 300 Hz (LF to MF) and 2 kHz (MF to HF) using 24 dB/octave Linkwitz-Riley characteristics.
• Max SPL: 140 dB (measured at 1m with a 10 dB crest factor using the [KUDO50] preset).

Electrical & Power Handling

The system is designed for quad-amplification, meaning each section (LF1, LF2, MF, and HF) is powered by a separate amplifier channel.

• RMS Power Handling:
  • LF: 2 x 450 W (8 ohms each).
  • MF: 312 W (8 ohms).
  • HF: 75 W (8 ohms).
• Amplification: Exclusively driven by the L-Acoustics LA8 amplified controller, which provides 4 x 1800 W into 4 ohms and includes dedicated DSP presets.
• Connectors: Two parallel 8-point PA-COM sockets.

Mechanical & Rigging

The KUDO features an integrated, captive rigging system that allows for both vertical and horizontal arraying.

• Dimensions: 876 x 356 x 689 mm (34.5 x 14 x 27.1 inches).
• Weight: 87 kg (191.8 lbs).
• Vertical Splay: Adjustable from 0° to 10° in 1° steps, with a maximum of 21 enclosures per array.
• Horizontal Rigging: Certified for up to 6 enclosures using the KLIFT accessory.
• Construction: Baltic birch plywood (15mm, 18mm, and 30mm) finished in gray-brown RAL 8019.

Operational Modes

• Full Range Mode: Used for standalone applications, providing a usable bandwidth of 40 Hz to 20 kHz.
• High-Pass Mode: Designed for use with subwoofers like the L-Acoustics SB28, optimized with a 100 Hz cutoff preset.
